There was a (now not so recent!) International Conference that developed the concept of a 3rd type of Diabetes. From that has come Type 3 variants (a-k) of which T3e was chemical or drug induced diabetes:
Type 3e diabetes. This form of diabetes is any diabetes that has been induced by chemical or drugs. For example, high doses of steroids, taken for an extended period of time, can lead to diabetes developing. Steroid-induced diabetes is therefore a form of type 3e diabetes.
We are gaining familiarity with the T3cs like myself; and so far the T3e variant is barely recognised by Health Care Professionals. However, a common misdiagnosis occurs by attributing T2 to people with diabetes brought about by the use of steroids. The fundamental start point is that once diabetic symptoms are picked up, the diagnosis should be led by the cause of those D symptoms and not by working backwards from the subsequent treatment path.
You don't say
@annieeast what specific treatment is being proposed for your D; but I have assumed that it is not by the use of insulin - since you don't mention that. However it is tricky to even comment on how you might best "navigate diet etc" without a little more information. Many T2s in trying to manage their D focus on losing weight and consequently visceral fat to give their pancreas a fighting chance of doing better; but some people can be Thin Outside and Fat Inside (TOFI). So weight loss may or may not be relevant. Exercise is a natural consequitur for losing weight and generally having a healthy lifestyle; so it's another option perhaps.
Then diet. Since all carbohydrates end up as glucose in your blood and potentially bring about the extra elevated BG then looking for a low carb [but NOT a no carb] diet seems a natural next choice. Our brain demands it gets glucose! So if our body is potentially starved of carbs, proteins and fats end up being metabolised into that glucose that our brains crave (demand). But the conversion rates are untidy (complicated) and ultra low carb diets can cause various sideffects. Hence low carb can be as high as 130 gms of carbs daily, but some settle for as few as 60gms daily. One recommendation is that if any main meal has 30 gms carbs then that is sufficient for the proteins and fats to be left alone.
Anyway, it would help to know a little more about your circumstances,
@annieeast, before making further comment or observations.
